A limestone cave with a total length of 600m
Abukuma-do Cave is a limestone cave that was first discovered in 1969 from the current remains of the Kamayama Quarry. The observation route within the cave is about 600m long but when including the routes that are not open to the public, the total distance amounts to about 3300m. This makes for the 11th-longest distance in Japan. Inside the cave, numerous stalactites formed over 80 million years of repeated erosion from underground water can be observed. This is a popular tourist spot where you can enjoy a strange and mystical view of the world.
Observe stalactites through the walking course
As you walk along the 40-minute observation course, you can fully enjoy the precious stalactites. View sights such as the Ghost Tower where ghost faces can be seen in the ever-changing area, the Silver Frost which evokes a scene of frost-covered trees, the huge stalagmites and small icicle rocks on the side that make up the Christmas Tree, the Mushroom Rock covered in flowstone, the precious Crystal Garden with its rocky patterns that can be seen if you look closely, the ring-shaped Cave Shield, and the White Porcelain Falls that resembles a flowing waterfall. Also, there are the 13m-high Dragon Palace and the Takine Palace which goes to the maximum height of the cave at 29m.
